Description of Magik (Illyana Rasputina):

She is a mutant sorceress linked to the demonic realm of Limbo, known in Earth's super hero community as Magik. As the younger sister of Colossus, she was tragically abducted to Limbo by the malignant Belasco when she was under the X-Men's custody. In the few seconds that passed on Earth, Rasputin aged years in Limbo, a process which caused her to master different dark arts. Following the manifestation of her mutant teleporting abilities, she was able to return to the X-Men and ultimately joined Professor Xavier's younger protégés, the New Mutants.
